Reduce dementia and NSAIDs

Exercise is powerful medicine for the brain for a variety of reasons and is vital for long term mental performance. Now more research suggests any exercise that increases heart rate will not only help prevent dementia but may also slow the progression. The Mayo clinic looked at the role of aerobic exercise in a 130 papers associated with brain deterioration in both human and animal studies. They say ‘there is a very compelling argument for exercise as a disease modifying strategy to prevent dementia.’ Brain imaging studies have consistently revealed that exercise generates trophic or growth factors that improve brain functioning and connections known as neuroplasticity. Indeed, a 70 year old person who exercises three times a week can restore their neuroplasticity to that of a 30 year old. Once again disuse is deadly and we are often too drug focused when helpful interventions already exist.

Talking of drugs, more concern over NSAIDs recently with the commonly prescribed painkiller diclofenac found in products like Voltarol. Regular use may raise your risk of a heart attack or stroke by 40% which is significant for those already at risk for example, if you have already had a heart attack, increasing age and conditions such as high blood pressure and diabetes. Six million people were prescribed diclofenac last year on prescription and you can also buy it over the counter-the latter, weaker version still raises risk by 22%. This study by Hull York Medical School was of 3 million people and further adds to the growing concerns of regular use of NSAIDs. As always no drug is costless or free of complications. However, people should never suddenly stop taking drugs but to consult their doctor if they are concerned.
